Answer:

Hi! I'm not quite sure what you entirely mean by this but I'll try to help. LxWxH is a formula used to find the volume of a rectangular prism or a box. If this is what you are using it for then there shouldn't a reason to divide. Unless maybe you're trying to find half of a box or you are trying to find the value of one of these in an equation but that's the only thing I can think of. Do you think you might be able to post an example in the comments?

Answer:

  14 units

Step-by-step explanation:

The two given points have the same y-coordinate, so lie on the horizontal line y = -8. The distance between the points will be the difference of their x-coordinates.

  distance = 10 -(-4) = 10 +4 = 14

The distance between the points is 14 units.

Step-by-step explanation:

Your calculations are correct actually 100% correct but may I ask where do you get a remainder of 17.

Because do you see where you have 118 - 102 =16 that is your remainder so you are correct but what the question was wrong.

Your answer is 13 with a remainder of 16.

You did a great job and didn't need my help but I do hope this helps have a great day:)

Answer:

m∠C = 98°

Step 1: Derive an Equation

To solve this problem, we will use what is called the Exterior Angle Theorem. This states that in a triangle, the measure of an exterior angle is equal to the sum of the measures of its 2 corresponding remote interior angles.

In this case, the exterior angle is ∠T (the obtuse one) and the remote interior angles are ∠C and ∠Y. Therefore, m∠T = m∠C + m∠Y.

Substituting the given measures into the equation, we get:

[tex]3x+2+x=130[/tex]

Step 2: Solve the Equation

[tex]3x+2+x=130[/tex]

[tex]4x+2=130[/tex] (Combine like terms)

[tex]4x=128[/tex] (Subtract 2 from both sides to isolate [tex]x[/tex])

[tex]x=32[/tex] (Divide both sides by 4 to get rid of [tex]x[/tex]'s coefficient)

Step 3: Answer the Question

We now know what [tex]x[/tex] is. Therefore, m∠C = [tex]3*32+2=\bf 98 \textdegree[/tex].

Answer: Is it B? I hope it helps you :)

Step-by-step explanation:

The equation to describe this situation is that Bobby's cat and dog were 6 miles apart after 30 minutes is 0.5x = 6

Since Bobby's cat runs at x mph, its speed is x mph.

Also, Bobby's dog runs twice as fast as his cat. So, his dog's speed is v = 2x.

Since they both move a distance in t = 30 min = 30 min × 1 h/60 min = 0.5 h.

Bobby' cat's distance in 30 mins is d = x × 0.5 h

= 0.5x miles

Also, Bobby's dog covers a distance in 30 min, D = v × 0.5 h

= 2x × 0.5 h

= x miles

Since Bobbys cat and dog were 6 miles apart after 30 min, we have that

D - d = 6

x - 0.5x = 6

0.5x = 6

So, the equation to describe this situation  that Bobby's cat and dog were 6 miles apart after 30 minutes is 0.5x = 6

Answer:

The mean is 6.2.

Step-by-step explanation:

The "mean" is the same thing as the "average". Essentially, the question is asking for the average of the numbers.

So:

Add up all of the terms. [6 + 11 + 5 + 2 + 7] = 31

You find the average by dividing the sum of the terms (31) by the number of terms (5).

31/5 = 6.2

The mean is 6.2.

Answer:

x=16

Step-by-step explanation:

so since a right angle is shown the it's telling that it's an isosceles triangle so you do 22-6=16

answer=16

The equation is written as x + 6 = 22. Then the value of the variable 'x' will be 16.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

From the figure, line AB is divided into two equal parts. Then the triangles will be congruent with each other by SAS postulates.

Then the side length (x + 6) is equal to the side length (22). Then the equation is given as,

x + 6 = 22

Simplify the equation, then we have

x + 6 = 22

x = 22 - 6

x = 16

The equation is written as x + 6 = 22. Then the value of the variable 'x' will be 16.
